In search of a suitable fuel alternative to fast depleting fossil fuel and oil reserves and in serious consideration of the environmental issues associated with the extensive use of fuels based on petrochemicals, research work is in progress worldwide,Thesourgarciniatreesarewidelyavailableandgrowintropicalregions ofAsiaand Africa and grow in semi evergreen forests of southern Western Ghats of India. The seeds fallen are collected and oil is extracted at village level with expellers, few million tons of oil will be available for lighting lamps in rural area. Growing Garcinia trees would also help in protecting the environment and benefit the farmers as well. The biodiesel produced by the oil of Garcinia is considered as one of the best substitute for diesel. The FFA test is conducted using titration method. As the raw oil consists of high viscosity and free fatty acid (FFA) the three stage standard transesterification method is used to produce biodiesel. The stage wise transesterification removes impurities, wax, gums, etc and the tri glycerides are converted into methyl esters and glycerine. The neat biodiesel is obtained after the removal of glycerine and water wash. Increase in awareness and growth in research in this area can motivate Garcinia gummigutta as the alternative source of fuel by replacing diesel. In the present study attempt has been made to develop the biodiesel from the oil of Sour Garcinia.
